The Brymen BT-71EU voltage tester comes from the BT-7XEU series and is the simplest meter in the series.
The voltage testers are easy to use tools to perform batteryless voltage detection. However,
they also feature a variety of battery-powered functions. With CAT III and CAT IV security, these meters can be connected to a power outlet without any worries.
The BT-71EU only has an indication LED that indicates what is being measured. The BT-73EU and BT-75EU have a display showing numerically the measured voltage, resistance or capacitance. The meters are automatically switched off to extend battery life. The BT-73EU and BT-75EU also have more features than the BT-71EU. For example, they can detect three-phase rotation and bar chart feedback of electrical field strengths. They can also be used as an RCD due to a built-in leakage resistance.
The models in this series differ from each other due to the presence/absence of certain functions, which can be seen in the table below.
|Display backlight & flashlight||✘||✔||✔|
|True-RMS ACV on numeric display||✘||✔||✔|
|AC detection shaker||✘||✔||✔|
|RCD leakage load for disconnecting circuit breakers||✘||✔||✔|
|RST phase sequence/rotation indication||✘||✔||✔|
|Capacity measurement function||✘||✘||✔|
|Resistance measurement function||✘||✘||✔|
|Measuring frequency||5 measurements per second|
|Dimensions||278 x 57 x 40 mm (l,w,h)|
